Physical properties
Mohs hardness of 6.5-7, pink to peach color, waxy to vitreous luster, microcrystalline quartz structure with botryoidal habit.
Formation & geological history
Formed via low-temperature precipitation of silica-rich groundwater within cavities of volcanic or sedimentary rocks over millions of years.
Uses & applications
Used primarily in lapidary arts, ornamental carving, jewelry, and as collector specimens.
Geological facts
The distinctive grape-like rounded forms are known as botryoidal growth, created by radial crystal growth from central nucleation points.
Field identification & locations
Easily identified by its curved botryoidal surface combined with underlying concentric banding, commonly sourced from regions in Brazil, India, and the USA.
